Are you guys going to help or just stare at the thread? I'm close to giving up. I'm so tired!

Ritalin I think.

ok, what's wrong now?

I figured that I need to have in-order traversal or something like this:


public void inOrder()
{
if (left!=null)
left.inOrder();
System.out.println(data);

My buildTree method might work but it seems to have several annoying cast errors.

Somebody please help!
